The power supply of the fully automatic resonance test device has the following functions:

1) The placement of variable frequency power supply is vertical and horizontal, which is particularly suitable for on-site operation and observation;

2) Equipped with special shock-absorbing rubber support feet and protective aluminum boxes inside and outside, it can effectively reduce the vibration during transportation and the impact during lifting. Ensured the long-term stability and reliability of the variable frequency power supply

3) Parameter display: The touch or external mouse large screen LCD interface display system can display resonance voltage (i.e. the target voltage set before the test), test frequency, measurement frequency, low voltage voltage, low voltage current, withstand voltage time, overvoltage protection, overcurrent protection, flashover protection, stage boosting and timing, operation mode switching, capacitance, inductance, frequency exchange calculation, parameter inquiry, etc. It can also display frequency curves, voltage curves, etc., which can intuitively judge the accuracy and stability of the resonance frequency of the current test;

4) Parameter settings: The large screen touch LCD color screen and external mouse can directly complete various parameter settings, including starting frequency, ending frequency, starting voltage, stage boosting and timing, measurement of voltage divider ratio, excitation ratio, overvoltage protection, overcurrent protection, flashover protection, test mode, capacitor inductance frequency exchange calculation, parameter setting prompts and assistance. 5) Test mode: Touch screen and external mouse operation, with three operating states: fully automatic, semi-automatic, and manual. Capable of boosting, tuning (including manual and automatic), segmented boosting and timing, and operating status

State, mode switching, fault prompt, capacitor inductor frequency exchange calculation function, etc.:

6) Protection function and its information prompt; Equipped with multiple protection functions such as high voltage overvoltage protection, low voltage overcurrent protection, overcurrent protection, as well as detuning protection, zero position protection, flashover protection, emergency stop undervoltage protection, etc. 7) Data storage function: saving test results (manually saved), printing, uploading, reviewing, etc. ① Test results: After manual or automatic testing is completed, detailed parameters of the test can be displayed in the test results interface. When the test is interrupted, the interruption status can be prompted. The parameters can be saved in a non-volatile memory that can hold 50 test records:

② Teaching data inquiry: It can display saved experimental result data on the screen and has a USB interface, which can output and print the data or use the printer carried by the device for printing; (The printer is optional for the customer, and if the customer has this requirement, it must be specifically stated in the contract)

8) Automatic voltage stabilization function: The system automatically tracks and maintains a stable test voltage based on the set test voltage or manual boost result, with a voltage stability of up to 1.0%. 9) The frequency range and frequency resolution can be set; The frequency modulation range can be set to 30~300H2, 45~100H2, 200~300H2, and can be adjusted as needed to accelerate the tuning process. The frequency splitting rate can be preset to 0.1H2, 0.2H2, 0.5H2, or 1.0Hz as needed, achieving an optimized balance between tuning efficiency and tuning accuracy; 10) Frequency adjustment is divided into coarse and fine adjustments, and can automatically find the test resonance point to ensure that the resonance frequency does not drift throughout the entire test process,.
